UNITED STATES CARL W. ART, OF SPOKANE, WASHINGTON.

CALCULATOR.

Application filed November 26, 1924. Serial No. 752,487.

To all whom it may con 0cm:

Be it known that I, CARL V. ART, a citizen of the United States, residing at Spokane, in the county of Spokane and State of l vashington, have invented new and useful Improvements in Calculators, of which the follov-ring is -.a specification.

This invention relates to improvements in calculators.

One of the features ofthis invention is to embody a calculator in a novel form wherein the result sought, will be invisible from that side or face toward which the user views the device when making the initial adjustment, and wherein the result will only be visible after the adjusted calculator has been reversed in position from its initial position. Tnus I embody in my improved device an element of surprise which is or may be capitalized-by associating with it the idea of fortune telling. This phase of the invention is advantageously emphasized by embodying the adjustable elements or members of the calculator either in the form of, or in attractive simulation of the usual playing cards.

While my invention is not limited to the specific form shown, still, it is a feature to equip the membersof the calculator with interdependent indicia whereby said members ma first be adjusted to denote the age of the user, and then further adjusted to de note the periodic savings. By then reversing the calculator, as thus far adjusted, the user will see totalized, the amount his savings would aggregate when he has reached a fixed advanced age. In other words, calculation is made of periodic savings or payments for a term .of years, irrespective of whether the savings or payments are directedto a bank account, an insurance policy, or analogous scheme.

Gther features and objects of my invention will be more fully described in connection with the accompanying drawings and will be increparticularly pointed out in and by the appended claims.

In the drawings:

Fig. 1, is a view in side elevation. of my improved calculator embodied in card form with the cards disposed in abutting registry.

2, is a view of the side reverse from that-shown in Fig. 1.

Fig. 3, is a view of the device looking at the obverse faces thereof and showing the initial adjustment of the selector card to a position denoting the age of the user.

Fig. is a view showing the second edjustment wherein the intermediate indicating card and the periodic card have been adjusted to indicate the periodic savings each month.

Fig. 5, is a View of the cards in the same adjustment shown in Fig. 3, but reversed in position so that the user is now looking at the reverse faces whereon is indicated the sum the user would have if he saved the amounts each month shown on the obverse faces in Fig. 4.

Like characters of reference designate similar parts throughout the different figures of the drawings.

I will now describe the specific form of my invention herein shown. First identifying the physical elements, a selector card is employed having an obverse face 1 and a reverse face 2, this card being one of the outer cards. An intermediate indicating card has an obverse face 3 and a reverse face 4:. A periodiccard hasan obverse face 5 and a reverse face 6, and thiscard is also one of the outer cards. These three cards are movably united .to be relatively adjusted out of lateral abutting registry, as shown in Figs. 1 and 2, into selective positions shown in Figs. 3 to 5, for instance. I preferably unite these cards by a pivotal connection as indicated at .7, and as shown, this connection 7 is located adjacent one corner of the cards and the arrangement is such that the cards open, when adjusted, in a gooddeal the fashion of a hand of playingv cards. In practice, I find it an advantageous feature to employ cardsof substantially the size and shape of playing cards and the free portions of the faces of said cards may advisedly be ornamented to simulate playing cards, therebycarryingoutrthe fortune telling feature. :However, my invention is not limited to the inclusion of these features and its utility as a calculator makes it capable or susceptible of'a widely differentrange of physicalembodiment.

Disposed and operable from the obverse face of the selector card is an opening 8 for disclosure therethrough of certain age indicative numbers. The selector card also has a registering edge 9, which is intersected by an index device preferably in the form of an arrow 10.

The indicating card has on its obverse face a series of age indicative numbers 11, affording a range from 26 to This of course is a very narrow range and has been shown thus limited in order to illustrate the numbers in large size for proper reproduction on a reduced scale. However, in practice, much greater range of age will be provided. These age numbers, as will be seen from 4, are disposed in concentric relation to the pivotal connection 7, so that as the selector card is adjusted, the opening 8, will consecutively disclose said age numbers. the same face 3, of the indicating earn 18 a series of connecting or continuity lines 12, which are preferably provided with enlarged terminals 13, for selective reglstry with arrow 10, next to edge 9, of the. selector card, These lines 12, at their opposite end terminate at ed 'e 15, of the indicating card. It will be noted that there is one connecting line for each age number,

On face 5, of the periodic card, are disposed a series of periodic or monthly sav ings numbers. These numbers are shown arranged in columnar form, the columnar lines 16 converging in a manner to laterally register with edge 15, as the indicating card is adjusted to various positions. These columnar lines are transversely intersected by lines 17, which are concentrically disposed with respect to pivot 7.

I will next refer to the reverse faces of the cards. The reverse face 6, of the periodic card may appropriately form the title face on which any suitable name of a bank or insurance company and its building may be disposed, together with the title given to the calculator.

The reverse face i, of the indicating card has a series of converging division lines 18, adapted for registry with edge 19, of the periodic card. Aggregate or total amount sums 20, are disposed between the division lines 18.

()n the reverse face 2, of the selector card is disposed an informative legend 21, with arrows 22, directing notice of the user to the largest sum adjacent edge 19.

I will next describe the manner in which the calculator is operated, and to facilitate such description, I will hereinafter designate the selector card by A, the indicating card by B and tie periodic card by C.

The user will dispose the cards as shown in Fig. 2, viewing face 1, of the selector card fr. He will next shift card A, to the left of the other cards, as shown in Fig. 3, until the opening 8 discloses an age number nearest the age of the user. Assuming that j the age is thirty, as shown, the index 10,

will register with connecting line 0. Now the user must next determine how much he can save each month, therefore.v he will retain the adjustment the cards A and B,

already made, and move card C, to the right of card B, until edge 15, and line a, registers with the amount which the user can save each month, which as shown, is $21.96. Now if he can save $21.96 each month until he reaches a certain advanced age, he will want to know, at a given interest rate, what he will have accumulated. Therefore, with the cards still in the adjustment shown in Fig. i, he will turn them around to view the reverse faces as shown in Fig. 5. He will til-en see that at the age of sixty-five years, he will have accumulated $20,000, and that will be his fortune, as told by this adjustment.

It will be noted that while the user is ad justing the cards and viewing the obverse faces thereof, he is observing the searching or finding indicia, whereas when he wants to find out what his fortune is, and reverses the cards, he will be viewing the answering indicia.

It will now be clear that there is a plu rality of adjustments necessary before the fortune can be told, first; the age or primary adjustment of cards A and B, relatively tb each other, and second; thedetermining or secondary adjustment of card C, relatively to card B.

The arrows 22, have a plurality of arrow heads properly spaced apart so that one will always be adjacent edge 15, and directmg attention tothe highest amount immediately adjacent said edge.

The device of my invention is primarily de signed as an attractive and interesting arresting token to be given out free by savings and loan institutions, banks, insurance companies and other concerns desirous of attracting the publics attention to the advan tages of regular savings. It will therefore be seen that while I have shown the device apparently designed for a bank, that it could easily be modified as regards arrange ,ment of the figures and legends to serve an insurance company, without departing from the spirit of my invention.

It is believed that the device of my invention will be fully understood from the fore.- going, and while I have herein shown one specific embodiment thereof, I do not wish to be limited thereto, except for such limitations as the claims may import.
